  • Popular Sweeteners and Their Health Effects Based Upon Valid Scientific Data
    Popular Sweeteners and Their Health Effects Interactive Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science By __________________________________ Ivan Lebedev __________________________________ Jayyoung Park __________________________________ Ross Yaylaian Date: Approved: __________________________________ Professor Satya Shivkumar Abstract Perceived health risks of artificial sweeteners are a controversial topic often supported solely by anecdotal evidence and distorted media hype. The aim of this study was to examine popular sweeteners and their health effects based upon valid scientific data. Information was gathered through a sweetener taste panel, interviews with doctors, and an on-line survey. The survey revealed the public’s lack of appreciation for sweeteners. It was observed that artificial sweeteners can serve as a low-risk alternative to natural sweeteners.

  • Full Assessment Report. (Word5)
    ATTACHMENT 3 SAFETY ASSESSMENT REPORT APPLICATION A406 PERMISSION FOR USE OF NEOTAME SUMMARY Introduction The NutraSweet Company is seeking approval for the use of a new artificial sweetener (Neotame) in Australia and New Zealand. The proposed uses include, but are not limited to, soft drink beverages (both carbonated and non-carbonated), beverage concentrates, beverage mixes, dairy beverages, fruit juice products, alcoholic drinks, non-dairy desserts, gelatin, ice cream, breakfast cereals and as a tabletop sweetener for use in hot beverages such as tea or coffee. Neotame (L-phenylalanine, N-[N-(3,3-dimethylbutyl)-L-α-aspartyl]-,1-methyl ester; or NC- 00723) is a dipeptide methyl ester derivative, chemically-related to aspartame. It has a sweetness potency of 7000 to 13,000-times sweeter than sucrose, and 30 to 60-times that of aspartame, depending on the use. Neotame was very stable in mock beverage solutions simulating commercial formulations. The only degradation product formed at >1% was L-phenylalanine, N-[N-3,3-dimethylbutyl)- L-α-aspartyl (NC-00751), which is also the major metabolite in both animals and humans and other minor degradation products (each <1%) which are not expected to be detectable at actual use levels of Neotame. Metabolism and toxicokinetics A number of studies on the metabolism and toxicokinetics were performed in rats and dogs, mainly via the oral route, although the intravenous route was also investigated. Neotame was rapidly absorbed following oral dosing, with around 14% of the administered dose absorbed in a pilot metabolism study and around 20-30% absorbed in the definitive rat metabolism study.

  • The Reality of Artificial Sweeteners
    Review Article Curre Res Diabetes & Obes J Volume 7 Issue 2 - May 2018 Copyright © All rights are reserved by Rafia Bano DOI: 10.19080/CRDOJ.2018.07.555708 The Reality of Artificial Sweeteners Rafia Bano* Department of Clinical Nutrition, College of Applied medical Sciences, University of Hail, Saudi Arabia Submission: April 04, 2018; Published: May 09, 2018 *Corresponding author: Rafia Bano, Department of Clinical Nutrition, College of Applied medical Sciences, University of Hail, HAIL, KSA, Saudi Arabia, Email: Abstract Now a days we are facing serious obesity issues worldwide. More than half of people in the US are becoming overweight, of which more than half are obese. As a result the weight related disorders are on the rise. So with all of these weight related problems going around, increased number of people struggling with weight lost regimens. They are trying to change their eating habits to include more vegetables and whole grains in their diets. They’re trying to be more physically active. They’re trying to modify snacking choices to healthier ones. There has been found an increasing trend of substituting artificial sweeteners in the sweet snacks and drinks that make up the majority of the American diet. But the question is that - are these substitutes really going to help? Or are they going to do more harm than benefit? The research has shown mixed evidences, but more and more is showing that these artificial sweeteners are not a good substitute. Artificial sweeteners continue to be a controversial public health issue, and the research keeps coming. At one side, many people are strongly opposing the use of artificial sweeteners because of the reported connections with increased risk for cancer and other metabolic and degenerative diseases.

  • Sweet Sensations by Judie Bizzozero | Senior Editor
    [Confections] July 2015 Sweet Sensations By Judie Bizzozero | Senior Editor By R.J. Foster, Contributing Editor For many, terms like “reduced-sugar” or “sugar-free” do not go with the word “candy.” And yet, the confectionery industry is facing growing demand for treats that offer the taste people have grown to love without the adverse health effects they’re looking to avoid. Thankfully, there is a growing palette of ingredients from which candy makers can paint a new picture of sweetness that will be appreciated by the even most discerning of confectionery critics. SUGAR ALCOHOLS Also referred to as polyols, sugar alcohols are a common ingredient in reduced-sugar and sugar-free applications, especially confections. Funny thing, they’re not sugars or alcohols. Carbohydrate chains composed of monomeric, dimeric and polymeric units, polyols resemble both sugars and alcohols, but do not contain an ethanol molecule. All but two sugar alcohols are less sweet than sugar. Being only partially digestible, though, replacing a portion of a formulation’s sugar with a sugar alcohol reduces total calories without losing bulk (which can occur when replacing sugar with high-intensity sweeteners). Unique flavoring, texturizing and moisture-controlling effects also make polyols well-suited for confectionery products. Two very common and very similar monomeric polyols are sorbitol and mannitol. Present in a variety of fruits and vegetables, both are derived from products of cornstarch hydrolysis. Sorbitol is made via hydrogenation of glucose, which is why sorbitol is sometimes referred to as glucitol. Mannitol is created when fructose hydrogenation converts fructose into mannose, for which the final product, mannitol, is named.

Abstract: Aspartame is a sweetener introduced to replace the commonly used sucrose. It was discovered by James M. Schlatter in 1965. Being 180–200 times sweeter than sucrose, its intake was expected to reduce obesity rates in developing countries and help those struggling with diabetes. It is mainly used as a sweetener for soft drinks, confectionery, and medicines. Despite its widespread use, its safety remains controversial. This narrative review investigates the existing literature on the use of aspartame and its possible effects on the human body to refine current knowledge. Taking to account that aspartame is a widely used artificial sweetener, it seems appropriate to continue Citation: Czarnecka, K.; Pilarz, A.; research on safety.

  • Sugar and Sugar Substitutes
    Sugar and Sugar Substitutes There are two types of sweeteners found in food and beverages: sugars and sugar substitutes. Sugars provide calories, or energy, for our bodies and increase blood glucose, as well as overall calorie intake. All carbohydrate-containing foods, such as breads, fruits, vegetables, milk, and yogurt, increase blood sugar, even if they do not have added sugars. How sugars appear on package ingredient lists: . Sugar . Dextrose . Corn syrup or High Fructose Corn syrup . Lactose . Honey . Sucrose . Glucose . Maltose Sugar substitutes (artificial sweeteners) provide little or no calories or carbohydrates and do not increase blood sugar. Therefore, choosing sugar substitutes can assist with controlling carbohydrate and energy intake. Sugar alcohols are also used to replace sugar in food. Sugar alcohols are incompletely absorbed by your body and contain about half the carbohydrate and calories as sugar. Sugar substitutes approved by the Food and Drug Administration: . Acesulfame K . Saccharin (Sweet n’ Low) . Aspartame (Nutrasweet/Equal) . Stevia (multiple brands) . Luo han guo fruit extract (Monk Fruit) . Sucralose (Splenda) . Neotame Sugar alcohols commonly found in food: Sorbitol, Mannitol, Xylitol, Maltitol, Isomalt Sugar substitutes … safe to use or not? Are you confused about the safety of sugar substitutes? Consider the following: Concern: Sugar substitutes may increase hunger or cause overeating at later meals. Be aware that studies have shown people are more likely to overeat foods prepared with sugar substitutes. Benefit: Sugar substitutes offer a sweet taste without increasing blood glucose or calories. If you have diabetes check your carbohydrate intake and adjust it to help control blood sugar. Choosing sugar substitutes is one way to assist you with limiting carbohydrate intake.

  • Sweet As . . . Sucralose: the Pros and Cons of Artificial Sweeteners 1
    Sweet As . Sucralose: The Pros and Cons of Artificial Sweeteners 1 Sweet As . Sucralose: The Pros and Cons of Artificial Sweeteners This article is a basic overview of artificial sweeteners, including what they are, why they are popular, and how they affect health. It is specifically intended for people with diabetes, individuals interested in lowering caloric intake, and other consumers wondering whether or not they should be worried about using artificial sweeteners. What Are Artificial Sweeteners? Artificial sweeteners are synthetic sugar substitutes that are much sweeter than table sugar (Mayo Clinic, 2015). While sugar has about 50 calories per tablespoon, many artificial sweeteners have zero calories. Six of the most popular artificial sweeteners approved by the Food and Drug Administration are saccharin (Sweet’N Low), acesulfame (Sweet One), aspartame (Equal, NutraSweet), neotame (Newtame), advantame (no brand name), and sucralose (Splenda). Acesulfame, aspartame, saccharin, and sucralose are several hundred times sweeter than sugar, while neotame is several thousand times sweeter than sugar and advantame is about twenty thousand times sweeter than sugar. As a result, you only need to use a very small amount to flavor your food (FDA, 2018). Takeaway: Artificial sweeteners are much sweeter than sugar but provide 0 or nearly 0 calories. What Foods Are They In? Many food companies use artificial sweeteners as low-calorie sugar substitutes in their products. If a food is labeled as “reduced sugar” or “diet,” this is a good indication that the product contains artificial sweeteners. If a product has artificial sweeteners, they will be listed in the ingredients section on the back of the package.

  • Appendix B Sweeteners
    Appendix B Sweeteners espite sugar’s insidious health consequences, it can be a hard habit to kick. That’s why science and industry have D come up with a variety of sugar substitutes, including artificial sweeteners, sugar alcohols, plant-based sweeteners, and alternative sugars. Here’s a cheat sheet to all your choices. Artificial Sweeteners Artificial sweeteners—such as sucralose (Splenda), aspartame (Equal, NutraSweet), acesulfame potassium (Sweet One, Sunett), and saccharin or cyclamate (SugarTwin, Sweet’N Low)—contain virtually no calories and, because they are generally hundreds of times sweeter than sugar, a little goes a long way. They are widely used in processed foods but also popular for home use. All are gen- erally considered safe for consumption in limited quantities. For those, myself included, who find artificial sweeteners to have an unpleasant aftertaste, sugar alcohols may provide an alternative. Sugar alcohols are, in fact, neither sugars nor alcohols, but a class of organic compound called polyols and include xylitol, erythritol, and maltitol. • Xylitol (Xyla) is perhaps the best known of the bunch. Used as a sweetener for more than a century (check your sugarless gum, Tic Tacs, or mouthwash—you may have been consuming the stuff for years), xylitol is derived from berries, mushrooms, corn- husks, and, in North America, hardwood trees, especially birch. It looks and tastes very similar to sugar but contains less than two-thirds of the calories and has a much lower glycemic index. And, like all sugar alcohols, xylitol isn’t metabolized by bacteria in the mouth, so it doesn’t contribute to tooth decay.

  • Non-Nutritive Sweeteners
    The REALTRUTH About Non-Nutritive Sweeteners Sugar, or sucrose, is one of the most widely used ingredients in the foods we buy. All other sweeteners basically are compared to how they stack up against sugar. Nutritive Versus Non-Nutritive Sugar and other sweeteners like fructose, dextrose, The Upside and the Downside lactose, maltose, honey, corn syrup and concentrated fruit juice sweeteners are called nutritive sweeteners. Sugar alcohols, including sorbitol, mannitol, xylitol, There are many benefits of using non-nutritive sweeteners. They: maltitol and erythritol, also are considered nutritive sweeteners. • Can contribute pleasurable sweet sensations without increasing energy intake. Nutritive sweeteners add energy (calories) to the diet. • Do not increase the incidence of dental caries Non-nutritive sweeteners don’t add energy. and may even prevent cavities. The FDA has approved five non-nutritive sweeteners: • Do not affect blood sugars. saccharin, aspartame, acesulfame-K, sucralose and • Decrease calorie content of food. stevia (the latest). • Can be used in non-food items to make them taste more pleasurable. • Can be used to replace sugar in cooking or What Do Dietitians Say? baking. • Only require small amount to sweeten foods The American Dietetic Association (ADA) states that and beverages. diet quality suffers when intakes of nutritive sweeten- • May aid in weight control. ers exceeds 25 percent of total energy.
